Radial Tonebone AC-Driver Acoustic Instrument Preamp

Studio quality preamp and class-A buffer circuit
Balanced DI output to feed a PA or powered speaker
Mute footswitch for instrument changeovers
Notch filter and phase switch to reduce feedback

The AC-Driver allows you to obtain great sounding results in a short amount of time, with powerful easy-to-use controls that allow you to set your levels and reduce on-stage feedback. An adjustable low cut filter removes excessive low frequencies, while a 180° phase switch helps correct feedback build-up from hot spots on stage. A variable notch filter targets and removes specific problem frequencies, and a mute footswitch provides a way to silently tune on stage or change instruments without any popping or noise in the PA.
